The touchstone was not men's needs, deeply as that took hold of His heart, and shaped so much His life. It was not the thought of service, though never was a life so filled with eager glad service. The touchstone was not natural liking or choice, the proper instinctive reach out of His true human nature, though this would be strong in Him, the typical Son of Man. This would not be repressed as an unholy or wrong thing. It would only be given second place, or left out, as it might run across the grain of the great life-passion. With a fresh touch of awe it may truly be said: He did not come down to earth primarily to die, though He knew beforehand that this would stand out as the great one thing. The death was an item in the obedience. He came down to do His Father's will. The path of obedience led straight to the hill of the cross, and He trod that path regardless of where it led. Obedience was the one touchstone of His life.[12] And it will be the one touchstone of His true follower's life. We shall run across this same vein of bright yellow gold, again and again, as we work on through this "Follow Me" mine. These were the three traits of our Lord Jesus' character upward, toward His Father. They were not different because of the emergency of sin He found in the world. They would have marked His life just as fully had there been no sin. But the presence of sin caused them to change radically the whole course of the life He actually lived. Sinless by Choice. Then there were _two traits of character inward_, in Himself. One was His _purity_. There was the absence of everything that should not be in Him. This is the negative side, though no part of His character called for more intense positiveness. Purity means sinlessness. He was sinless. But we must quickly remember what this means, or else there may seem to be no following for us, only a wistful gazing where we cannot go. It does not mean simply this, that through His peculiar birthright there was freedom from all taint of sin.
